My iMac is driving me crazy. I have an iMac C2D 2.16 GHz with 1 GB of RAM and the Apple wireless mouse and keyboard. At least half the time when I boot up, the clock and other components on the right side of the menu bar will freeze (but the Gmail notifier still works), and the spinning beach ball will appear over the right area of the menu bar. When this happens, you can't browse any folders or perform any tasks in the Finder, but launching apps from the dock still works. It was doing this before the 10.4.10 update and has continued after the 10.4.10 update. I uninstalled Parallels because I heard that it modifies the kernel, and wanted to eliminate the possibility that it was causing the problem. I tried doing an archive and install of OS X a few weeks ago (and then installed all the updates), but that hasn't helped. I will check the console log and make another post once I reboot--I can't get to the console right now because Finder is locked up. This is really frustrating--my PowerBook G4 has essentially the same software installed and is as solid as a rock.
